To all whom t may concern.'

Be it known that 1,'HARRYEBERT, a citizen of tliejUnited States,residing at Frederick, in the county of Frederick and State of Maryland,have invented new aiidnsefull Improvements in Shutter-Latches, of whichthe following is a specification.

rl'his'invention relates to shutter bowers,

and has particular reference to an improved means for automaticallylatching or locking the shutter when the Asame ,i is swung into closedposition.

The object of the invention is to` provide a simple shutter latchingmeans, the maj or portion of which ismounted upon the sill ofthefwindowframe; a latching means which is of very simple construction,which may be economically manufactured, which is composed of relativelyVfew parts occupying but small space; which is easily applied to theblind to take* the place of the attachments at present in use; and alatching means which may be quickly released by the depression of one ofthe membersthereof.

@therV objects and advantages of this invention will be brought out iirthe following detail description of the present preferred embodiment ofthe invention,the same being illustrated in the accompanying drawingswherein,-

Figure 1 is a horizontal section through the top of a window showing ablind in open position, and also showing the improved latching meansapplied thereto. Fig. 2 is a similar view showing the blind in closedposition, and showing the improved latch locked. Fig. 3 is aninsideelevation of the same. Fig. 4 is a detail fragmentary view,

` showing in inside elevation the latch member released. Fig. 5 is atransverse section through the window frame, the latching Vplate, andblind; showing in side elevation the latch in the position of Fig. 4.

Referring to this drawing, wherein like parts are designated by similarcharacters of reference throughout the several views, 10 designates awindow frame having a sill 11 and supporting at Y,one side a hingedblind 12. The blind 12 is provided with the usual bracket 13 carrying apivoted bower rod 14 which, as shown in Fig. 1, engages in a socket 15mounted on the sill 11 to hold the blind 12 in open position.

Near the outer edge, and at the bottom of the shutter 12, a hook 16 ismounted the saine projecting inwardly and having a down.

wardly extending bill 17 the outer face of which is beveled, as shown toadvantage in Figs. 4 and 5.V y

Mounted on the sill 11, and registering with the hook 16, is a `springlatch plate 18 having one end thereof returned in spaced relationbeneath the plate to provide a base 19 for permanent attachment to thesill 11 and adapted to hold the plate 18 normally and yieldingly inspaced relation above the sill 11, as shown in Fig. 3. As the plate 18is a spring plate the same is provided near its outer free end with aregulating screw 20, theV same passing down through the plate and intothe sill 11. The head of the screw 20 limits the upward springing of theouter end of the plate, and thus holds the plate in the desiredhorizontal position. As shown in Figs. 1 and 2, the spring plate 18 isprovided with a plurality of openings 21 adapted to receive the .freeend of the bower rod 14to hold `the shutter 12 in various closingpositions. upon-the blind 12 that the bill 17 thereof registers withyone of the openings 21, as shown clearly in Fig. 2, so that when theblind 12 is closed the hook 16 engages in the said opening21 of thespring latch plate 18 and locks the shutter 12 in closed position.

As the outer side or face of the bill 17 of the hook is beveled, thedrawing of the blind into closedposition forces the bill 17 against thespring plate, and the free end of the spring plate 18 is flexed downinto the position shown in Fig.r4. This admits of the riding of the bill17 over the upper face of the spring plate 18, and when the billregisters with the said opening 21, the plate by its inherent springaction rises to its normal position and secures the bill 17 of the hook16 in the opening. `Wlien it is desired to release the blind to open thesame, all that is necessary to do is to depress the free end of thespring plate 18, such as by depressing its outer end at the point 22, inorder to move the plate down out of engagement with the bill 17 andadmit the hook escaping the marginal edge of the opening 21. The blind12 may now be pushed outwardly into open position.

The hook 16 may be provided, as shown in the accompanying drawing, withupwardly extending fingers 23 and 24, the finger 23 serving as a handgrasp to swing the shutter 12 into the desired position, while the otheriinger 24 serves not only as a rThe hook 16 is so positioned fingergrasp but also as a support for the free end of the bowing rod 14 whennot in use.

lt will be noted that in the present preferred embodiment of theinvention theV hook maybe a casting secured to the blind 12, while thespring plate may be made of a strip of flexible material suitablyapertured and bent into the desired form. The

base 19 is fixed to the sill 11 by a screw or the like, while its freeend is held in the de- Y from the spirit thereof, such changes beingrestricted only by the scope of the following claims. Y

YWhat is claimed is 1. In combination with a window easing,

and a shutter hinged thereto; a depending hook carried upon the innerside of thev shutter andV having a beveled edge facing inwardly when theshutter is closed; a spring plate secured at one end vin spacedrelationv to the casing having an opening near its free end in registrylwithY the hook, said beveled edge of the hookbeing adapted to strikethe'outer edge ofthe spring plate and to depress the free end'thereofupon the closing vof the shutter, said spring plate being adaptedgtospring upabout thehoolV upon the passage of the hook into' saidopening,anda regulating screw carried by the casing engaging with vthe 'free .yend of the plate to limit the upward springing and the lateral swingingmovement of the plate.

2. A shutter latch comprising ahookV adaptedfor securement to the innerside and at the bottoni of a shutter, and having a depending beveledbill, Va springplate havhaving an extensiony on Aits free end adaptedVAfor engagement by the finger to depress the plate and release the hook,"j l In testimony whereof I have hereunto set my hand in presence of'twosubscribing witnesses.
